f(x) = 6x - 4 + x^2

We complete the square to get vertex form.

f(x) = x^2 + 6x - 4

f(x) = x^2 +6x + 9-9- 4

f(x) = (x+3)^2-13

<span>The vertex form of the function is f(x) = (x – 2)2 + 2.

Nope.

The vertex of the function is (–3, –13).

Yes, that's easily seen from the vertex form we got.

 The axis of symmetry for the function is x = 3.

Nope, x = -3 is the symmetry axis.

 The graph increases over the interval (–3, infinity).

That's true; the minimum is at the vertex when the squared term is zero and it increases both ways from there.

The function does not cross the x-axis.

No, it does cross; its minimum is -13 and it goes up from there.

on the average deepa drinks 4/5 of a 6 ounce glass of water in 2 4/5 hours. how many glasses of water does she drink in one hour
lesya [120]

Answer:

1 5/7 glasses

Step-by-step explanation:

4/5 of 6 ounces is 24/5 ounces

24/5 ounces in 2 4/5 hours equals 'x' ounces in 1 hour

(24/5)÷(14/5) = x/1

cross-multiply:

24/5 = 14x/5

70x = 120

x = 12/7 or 1 5/7

The sum of two numbers exceeds their product by one.Their difference is equal to their products less five .Find the two numbers
Ludmilka [50]

Answer:

1 and 3

Step-by-step explanation:

If the two numbers are x and y, then:

x + y = xy + 1

x − y = xy − 5

Subtract the two equations:

(x + y) − (x − y) = (xy + 1) − (xy − 5)

x + y − x + y = xy + 1 − xy + 5

2y = 6

y = 3

Solve for x:

x + 3 = 3x + 1

2 = 2x

x = 1

The numbers are 1 and 3.

Solve for y. 2(3y-7)=16​
Nimfa-mama [501]

Answer:

y=5

Step-by-step explanation:

First, distribute the 2 to the 3y and -7

6y - 14 = 16

Second, add 14 to both sides.

6y = 30

Third, divide both sides by 6

y = 5

As you can see y equals 5!

I hope the explanation helped and have a great day!
